THOMAS WALBRDGE, Ol*1 TLEDO, OlllO.

Application filed october 29, 1966.

To all who/m it' Imay concern:

yBe it. known that l, AT1-reims lfl. lli/'inf manon, ot Toledo, Ohio, have invented a certain new and useiful lmprovemeut in Axles, whereotl the following is a specification, reterence being had to the accompanying drawings. i

il; improvement particularly' applicable to .#.Xles of the type en'iployed in carriages, wegens, automobiles and similar vehicles, wherein the vehicle supporting wheels-are rotated independently ot the axles which are preventet from rotating by connection with the vehicle body.

lt is an object of my invention to provide an axle which may be constructed of corn- I and, the .term of my invention hereinafter described comprises an axle tormedof a commercial metal tithe of circular cross section provided with screw 'threads at its ends, and abutments for the wheels carried by respective sleeves of polygonal cross section which 'are rigidly secured on said tube and which 'form seats for respective spring connection with the shit' i body.

s hereinafter described, l lind venient to l'orui the screw threads. at the ends oit the arde upon metal plugs ihich are rigidly secured therein, and to yrovide said sleeves with circular portions concentric with the axle tube and extending outwardly beyond the wheel alnitments solas to reins torce the axle within the wheels.

My invention comprises the various novel features of construction and arrangementhereinat'ter more definitely specilied.

ln the drawings, Figure l, is a longitudinal sectional view ot an axle conveniently embodying my improvement. Fig. ll, is a` transverse :tional view of said axle, taken on the line ll, lill, in Fig. l. lEig. lll, a sectional view similar to Fig. l, but showing a inodilicd :torni ot arie with a hub applied thereto. Fig. lV, is a transverse sectional the axle, talrcn on the line lV, lV,

oT inlfin. i i Fig. V, is a transverse sectional the line V, V, in

it conriewlrt the axle taken on lll.

' ring to l, and lil', the axle comprises the structural metal tube l, which is conveniently tnined et a strip et sheet steel bent in cylindrical its opposite torni with edges meeting as indicated at in Fig. l. Said edges may he welded, brazed or otherH wise joined.v Said tube l, is provided at Patented June 22, 1909.

Serial No. 340,975.

each end with a screw thread 3, to engage a wheel retaining nut t, and a vflange abutment 5, which respectively determine the position ol' the wheels on the axle. As shown said flange 5, is formed in unitary relation with the sleeve 7, which is rigidly secured on said tube l, and is preferably seamless as indicated in Fig. ll. AS indicated in Fig. ll, said sleeve 7, is rectangular in cross section and its upper wall 8, forms a seat for the spring connection between the axle and the vehicle body.

ln the l-orm ot my invention shown in Figs. lll and lV, the axle comprises the tube 10, which is similar to the tube l, shown in Figs. l and Il, but the screw thread 11, at the end thereof is conveniently formed on the plug l2, which tits within said tube and is rigidly connected therewith. Said plug l' may he welded within the tube 10, or the latter may be expanded, by heat, and shrunk vrupon said plug.

The abutment 14, which determines the location ot the wheel in Fig. III, is a flange projecting transversely with respect to the axle .in unitary relation with the sleeve 15. Said sleeve l5, is of polygonal cross section atil's portion lo, said flange 14, as indicated. in Fig. IV, but its portion 17, extending outwardly from said llange llt, is et circular cross section as indieated'in Fig. V, and lits within the Wheel huh 18, so as to reinforce the aille where it supports the bearing balls 20, in addition to affording a seat for the spring connections between the axle and the vehicle.

Although l Find it convenient to vform said sleeves 7 and 15 of rectangular tubes, it is to he understood that they may be forme oli tubes of other polygonal cross section, capable of atlording a suitableseat for the spring connections.

l do not. desire to limit myself to the specilic del ails ot construction above described, as itv is obvious that various modifications may be -made therein without departing from the scope ol the following claims.

A vehicle axle formed of a. split cylindrical metal tube provided with screw threads at its opposite ends; seai'nless sleeves secured on said tubo forming wheel abut ments and seats tor spring connections; said sleeves being ot uniform internal diameter, but circular at one end, and polygonal at the other; and, radially projecting c1rcumterextending' inwardly from' ntia {ianges ai, the jimiioms of tho oylinclxlca and polygom porlons of shapes,

Substam; Hy s e forth.

2 A x o wie axle formof of a spit oylmpojectng circumferential.

on mid "aube forming Whee abutmemllts and seats for spring connections; said sleves being of unorcm internal diameterA but circular si one and, and polygonal at thother; and, radiay project-ing circumferential Songes ai: ho junctions of the .cylindrical and po ygona portions of: said Sleeves, substanta 1y as Set forth.

n testimony whereof, I have hereunto signed my name at Toledo, Ohio, vthis sevenl'eenth day of October 1906.
